Question

我尝试使用下拉标记获取地图（每个都有信息窗口）。多个标记必须以HTML / CSS按钮开头。 Infowindows应该有不同的文字。即使在每个信息窗口使用相同的文本，我也无法构建。在控制台浏览器中，我看到消息：＆＃34; SCRIPT445：对象不支持此操作＆＃34;。我根本无法触发Infowidow。我在Google示例/中使用的代码如下：

 <!DOCTYPE html>

                padding: 0;
              }
              #map {
                height: 100%;
              }

Answer 1

你只有两个小错字。

在script标记中。网址中的?和js之间应该有signed_in：

<script async defer src="https://maps.googleapis.com/maps/api/js?signed_in=true&libraries=places&callback=initMap">

然后，在代码示例的末尾，您的html标记缺少结束>。

如果你解决了这两个问题，你的地图就会加载。

Answer 2

最简单的解决方案，将所需的HTML传递给addMarkersWithTimeout函数并使用函数闭包（就像在Google Maps JS API v3 - Simple Multiple Marker Example的答案中所做的那样）将标记的内容与click事件相关联该标记的监听者：

function addMarkerWithTimeout(position, html, timeout) {
  window.setTimeout(function() {
    var data = position;
    var marker = new google.maps.Marker({
      position: position,
      map: map,
      title: data.name,
      animation: google.maps.Animation.DROP
    });
    markers.push(marker);
    var infowindow = new google.maps.InfoWindow({
      content: html,
    });
    google.maps.event.addListener(marker, 'click', (function(marker, html) {
      return function() {
        if (this.getMap()) {
          infowindow.open(this.getMap(), this);
        } else {
          infowindow.close()
        }
      }
    })(marker, html));
  }, timeout);
}
